I've got that kit to build 2" headers, Bill. I don't know if they'd be any good but we can try something. You want them between the frame rails, all the same length tubes, good clearance for easy spark plug removal and easy to get the bolts out...in an A Body? Sounds easy.
sound's about right,,,oh and don't forget easy installation with no loss of knuckle meat.LOL
Light travels faster than the speed of sound,,,this is why some people seem bright untill you hear them speak.
